COIN-CONTROLLED MACHINE.

Application mea apra a4, 1922. seran No. 556,259.

This invention relates to means for operating article-delivery devices after the insertion` of a predetermined number of checks or coins, and its object is to provide a comcontrolled mechanism'whereby the positioning of a stop determines the number of coins which must be deposited before the article- I a right side elevation of the coin-controlled mechanism when removed from its case. Fig. 2 is a left side elevation and Fig. 3 a front elevation of this mechanism. Flg. 4

is a leftsideelevation when the main supporting plate 1s removed. Fig. 5 is a view similar to Fig. 1 with partial cover plates reinoved. Fig. 6 isa section on bthe line 6-6 of Fig. 1. Fig. 7 is a detail showing the change-testing key. Figs Sand 9 are diagrams ofthe change releaser in two positions. Figs. 10, 11, 12 and 13 are sections on the lines 10-10, 11-11, 12.-12 and 13-13 of Fi 1 respectively. Y

Similar reerence characters refer to like The mechanism shown in the drawings i's intended to'be attached to any desired type of article-delivery mechanism which is acy tuated orcontrolled by a manually-operated that'actuates the several parts of this coin-'controlled apparatus. This lever isnormally prevented -from moving a sufficient distance to operate the other mechanism by a swinging frame, but this control frame is v rendered inoperative by the insertion of the -predeterminednumber of coins of lower denomination or uponf the insertion of a single coin of higher denomination7 depending upon the sales value of the articles to be sold.

Provisions are'made whereby the operating lever may be released by the insertion of the coin of higher denomination and the delivery of the proper number of coins of the lower denomination or vthe change should 'the nickels pass down on the right side of .operating lever, a rack bar 17 is attached to the selling price of the article be below the 66 value ofthe coin of `hi her denomination.

vIn tliepresent case the coin of higher denomination is the nickel five cent piece and those of lower vdenomination are cents. Provisions are made to hold a number of cents in the change receptacle so that change can be. made for the nickel.. This changef receptacle is automatically, filled when cents are deposited for operating the device. In the present case, the machine is set :for articles to be soldv at three cents each and for the change makerlto deliver two cents to the person` inserting a nickel. Means are also provlded whereb an intended purchaser may determine w ether the change maker has the proper number of cents to make change.

' The machine is built on a supporting plate 1 to which guide plates are attached and a partition plate' and smaller cover plates are attached to the guide plates. The cents pass down on the right side of the plate 1 and between it and thepartition plate 2, while this partition platet The movab e parts of this machine are actuated by an operating handleJ '3 which connects to the two side levers 4 and 5 which are mounted at their rear ends on a pin 6 extending through the several plates and guides. It is to be understood that one-of these two levers may be omitted but that two are preferred as the operation is more balanced.

Attached to the lever 4 on the left side of the machine is a pin 7 which represents the connect-ion between this coin-controlled mechanism and the article-delivery mechanism to which itis attached. Connecting rods 8 and 9 extend' up from pins 10 on these levers to the pin 12 which' extends through guide slots 13 in the4 several plates and through holes in the coin .pushers 14 and 15 which force down the coins.

In order to compel a full stroke of the the plate 2 and a pawl 18 is .pivoted on the .pin 19 on the lever 5, the pin extending through a block 20'on the outer side of the lever 5 and ainger 21 projecting rearwardly from this block and connecting to a spring 22 which is hung on the pin 23 on the lever 5. The pawl prevents the lever from bein reversed until 'the pawl has entirely passecgl lin dott-ed lines,

overV the `rack so that it may be swung to extend from the opposite side of the lever 5.

On the plate 1 is an extension 24 on which the disk is mounted, and on each side of the partition plate 2V are the runways 26 and 27 to receive the cents and nickels-respectively. The plate 1 is provided with a slot 28v through which the cents may be observed.

upper edge 33 and rear edge 34 areparts of..

the cent race, and .which is formed with irregular rear edges 35 and 36 to co-operate.

with the front edges of the third .spacer plate 37 to constitute the change receptacle con- Sisting of the upright parts 38 and 39 and the inclined parts 40 and 4l. The upper edge 43 and rear edge 44 ofi the plate 37, co-operate with the edges 45 and 46 of the fourth plate 47 to'constitute a chute 48 for the cents not needed for making change that is, Aafter the change receptacle is filled, the cents roll down the chute 48 to the opening 49 and down the guide 50 to the cash box.

Attached to the plate 1 is a cross bar 52 (Fig. 4) which carries avpin 53 0n which the sale controller is'suspended. A spring 54 (Fie. 1) connects to this controller and normal y holds it forward, .This controller` i consists of .a bar 55 on which aseries of screws y56 are rotatably mounted. These screws operate the nuts 57 to which l.the fingers 58 are attached and these'nuts are slidable in notches 59 in this bar. is rigidly attached to the barg 55 below the fingers 58 and each. finger has a beveled forward end, In the present case, the fnachine is setfor three-cent sales. The third finger 58* from the top is therefore moved'inward into the upright portion of the cent chute It may be said that the rear side of this chute is formed bythe small plates 61 and 62 between which the fingers extend. The inner ends ofthe screws 56 are mounted inthe bar' 63 Fig. 1).

en the parts are as positioned inFig. 4, and threecents have been inserted inthe slot 26 and rolled down to the positions indicated l a depression of the operating lever and of the pusher 14 will force the coin'sgdownward and cause enough pressure on the finger 58l toswing back the sales controllen. Le

Fig. v1 shows the operating llever swung down without a sufiicient number of coins being placed in thecoi'n'receptacles to swing back the sales controller. The link 9 vhas a finger 66 which extends over the finger 67 on the arm 68 at the outside ofthe lower end of the sales controller. When the parts are A finger 60 as shown in this figure, the operatin lever cannot be depressed any further. ut if a suflicient number of coins'were previously supported by the finger 58, thedepression of the lever would swing this controller and the arm 68 andflnger 67 yout of the path of the finger 66 before the finger 66 reached the position shown in Fig. 1, and full operation of the lever 5 is permitted. The full stroke device 174-18 now forces the lever to move down its full distance before it can again resume its normal position.

W' hen a nickel is inserted, the Tnechanism shown in Fig. 5 is employed. The Dpartition 2 has an extension 27 and to this plate and its extension the guide platesf70, 71, 72, 73, 74 and 75 are attached, forming a runway for the nickels extendiner from the collar 25 to the opening 76 in the partition, which opening registers with the opening 49 in the side plate 1. There is only one finger 7 7 extendin into the upright -portion of the runway rom its support, the lever 55, into the paths of the nickels and this finger holds" the inserted nickel until the coin is forced down by the pusher 15 at which timethe coin swings the lever 55 to the rightin Fig. 1

nand carries the finger 67 out of the vpatlizof the finger 66. f The plates 79 and 80 form the outer wall ofthis 'coin chute.

The change maker is operated by the inserted nickels' and controls the cents in the change receptacle. A pin 82 'is mounted in the partition 2 and in a small plate 83 shown 1n Fig. 1. A lever 84 is mounted on this pin and has a flat thin hyead 85 at its upperend in the plane of the runway for the nickels, the lever itself being somewhat thicker. The spring 54 connects to the pin 86 and holds the head 85 in' the path of the nickels but permits the lever to swing to the position shown in dotted lines in Fig. 5. v

Mounted' on the lower arm 87 of this lever are a. series of screws 88 which extend through slots 89 in the-partition plate.and these screws are of such length f that their -inner ends are adalted to extend into the change receptacle. ee Fig. 11. Springs 90 on these screws prevent them from turning. As the article to be sold is to bring three centsftwo cents are to be given in change for -each nickel inserted and therefore the `point of the next to the lowest screw 88a ismoved into the change receptacle.

Three cents -in the chang* receptacle are normally supported by a dis 92 rotatable on the pin 93'between plates L'and 2 Aandrotatable by means of the crank pin 94 rigidly through the slot 98 into the slot 95 of the arm 96 at the. lower end of the arm 87 of the change maker. This arm 87 is guided by a bar 97 (Fig. 1) and the crank pin '94 extends through a slot 98 in the partit-ion 2. The lower end of the bar `9 may be guided llO connected to the disk 92 and extending l swung toward the change receptacle,

-431 and swing towardthe ed e 34",

by a plate 99 but it is 4spaced farther apart d the edges 43 and 45. The corner 34b is preffrom' the plate 2 than the change maker an so does not interfere therewith. The pin 94 which is mounted in the disk 92 and extends through the slot 98 in the partition 2 and through the slot 95 in the arm 96, projects far enough beyond thi arm to be in the plane of the ilower end the. bar 9. `When a nickel is inserted d is pressed downby the part 15 again t the head 85, this pin will be swun to the position shown in dotted lines in i 5 before the lower end of b'ar 9` reaches t e path ofthis pin. Thereafter the bar passes down to the left or in front of this pin in Fig. 1 and prevents the return of this in until the operating lever has made full own and up strokes. This gives ample time for the change to pass down the passage 39 and out through .the guide way 102.

When cents are inserted, the arm 87 is not swung, and the bar 9 is moved down so that its lower end passes back of the pin 94 (to the right thereof in Fig. 1). So long as the operating lever is making its down and up'` strokes, this pin and the disk 92 are kept from moving so that the change rece tacle is kept closed by this disk and no disc arge is permitted while the bary 9 is down.

When the nickel is forced down by the pusher the coin swings the lever to the position shown in dotted lines inFig. 5 and this carries the disk 92 from the position shown in Fig. 8 to that shown in Fig. 9. In Fig. 8 this disk is shown supportin a series of cents A, but when the change ma er is operated, this disk is turned until its straight side 100 is vertical and thus permits the discharge of the cents. When the arm 87 and the screws 88 are the de pressed screw 88a moves into the s ace between the second and third cents rom the bottom and prevents all but two of the cents from falling out until the disk 92 is again in normal position. The number of cents to be given in change is therefore determined by 'the screws 88 and the number ofcents the article is to bring is determined by the screws 56.v The change goes down the chute 102 into the small receptacle 103 from which it can be removed by the purchaser.

If the wall 34 were straight down to the edge 35 of the plate 32, the cents along the edge 43a might pile up until above the point 45'which would cause clogging ofthe machine. The vertical edge 34 of the plate 32 is therefore cut back at 34a and the edge 43'* is advanced so that the upper coin C 1s not in alinement with the coin chute above it -but a little on one side of this chute. De-

the corner l and when the coin receptacle is filled, t e upper coin C scending coins normally strike is at one side of the path of the next coin contacting with t 1e upper coin C inthe coiny receptacle.

Figs. 4 and 7 show the details of a device for determining if there are sufficient coins in the change receptacle. A button 104 on the rod 105 is adaptedto push the rear end of this rod against a coin. A small plate 106l is mounted on the pin 108 and has a curved plate 110 at its outer edge (Fig. 3).. This plate 106 is connected to the ro 105 by a pin 111 and the parts are held inlthe position shown by the spring 112. Any desired letters may be placed on the curved plate 110, to be show when. the rod 105 strikes a coin or when it is unobstructed and moves entirely inward. y,

As stated before, the side plate l has an extensi 24 and a slot 28, the partition 2 has an extension 29 and a slot 30, and the plates 31 and 32 are between the plate 1 and the partition 2 and form a runway 33. Secured to the partition 2 are the plates 70 and 71 and they form the runway the plate 79 is secured to these lates and 69, and

has aslot 78. See Fig. 9.' Attac ed to the plate 79 is an apron 114 on which rejected coins may slide out ofthe machine.

When a cent is placed into'the runwayl 33 it will roll into the machine, but a dime will 4slip out sidewise. A nickel will roll into the l 4machine in the runway 69 but smaller coins will lfall out sidewise onto the a ron114 and slide out of the machine. .This mecha- Vnism therefore prevents the insertion of a .parts of this device may all be changed by those skilled inthe .art without departing from the spirit of my invention as set forth in the following claims.
